For the love of God, don't use PureVPN! They have been proven in court to log traffic, despite claiming not to.[1]

Two other VPNs working for this purpose are OVPN (+1 for them using WireGuard, but their Singapore node is slow) and SwissVPN (limited to only 30 Mbps by contract, but they do provide these contracted 30 Mbps).
